Tripp Lite USB 3.2 Gen 1 to Fiber Optic Gigabit Ethernet Adapter with Open SFP Port

Upgrade your workspace with a turnkey USB-to-fiber solution that brings high-speed Gigabit Ethernet right to your desk. The Tripp Lite by Eaton U336-1G-SFP is more than a simple USB adapter; it’s a flexible, future-ready link between USB devices and fiber networks. Built for fiber-to-the-desk deployments, this adapter lets you unlock the performance and reliability of fiber optics without ripping out your existing devices. Whether you’re equipping a home office, a corporate workstation, or a remote branch, this device makes it easy to extend your fiber backbone exactly where you need it, delivering consistent throughput, improved security, and reduced electromagnetic interference compared with traditional copper Ethernet.

• Seamless USB-to-fiber bridge: Turn any USB-A computer, laptop, or tablet into a robust fiber-connected endpoint. This adapter leverages USB 3.2 Gen 1 to provide ample headroom for Gigabit Ethernet traffic and smooth multimedia streaming, software updates, and large file transfers over a fiber link.
• Open SFP port for flexible optics: The U336-1G-SFP features an open SFP port that accepts compatible singlemode or multimode transceivers. This design gives you the flexibility to match your existing fiber infrastructure, choose cost-effective transceivers, and scale your network as needs evolve—without being locked into a fixed module.
• 1310 nm performance for long-haul and campus use: The included 1310 nm optics are ideal for many campus, enterprise, and data-center scenarios. This wavelength provides efficiency and low dispersion over standard fiber runs, helping maintain signal integrity across moderate distances while supporting reliable Ethernet speeds.
• Compact LC connector for a tidy setup: With an LC duplex connector, the adapter integrates neatly into compact office racks and desktop arrangements. The LC interface pairs with common fiber cabling and transceivers, enabling clean, reliable connections in dense work environments.
• Designed for fiber-to-the-desk deployments: Specifically engineered to bring fiber connectivity right to individual workstations, this adapter helps you modernize networks without reworking cabinets or sprawling switches. It empowers IT teams to extend fiber benefits—lower latency, greater bandwidth, and improved immunity to electrical interference—directly to each user.

How to Install Tripp Lite USB 3.2 Gen 1 to Fiber Optic Gigabit Ethernet Adapter

Install this adapter quickly and confidently to unlock fiber connectivity from your USB-enabled device. The steps below assume you have a compatible SFP transceiver and fiber cabling on hand.

• Select and prepare your SFP transceiver: Choose a compatible SFP module that supports 1310 nm operation for singlemode or multimode fiber, depending on your network. Confirm the module is rated for your cable type and distance requirements, then insert it firmly into the open SFP port on the adapter until it seats.
• Connect fiber cabling: Attach the LC fiber cable to the transceiver, ensuring a solid click and secure alignment. Route the fiber cable to the destination network device (such as a switch, router, or patch panel) and connect the other end to the corresponding fiber port.
• Link the USB side: Insert the USB-A connector into a USB 3.2 Gen 1 port on your computer, laptop, or tablet. For optimal performance, use a dedicated USB port rather than a shared hub, and avoid daisy-chaining other USB devices that could create bandwidth contention.
• Configure the network: Depending on your OS, you may need to install a driver for the Ethernet function or rely on the operating system’s built-in drivers. In most environments, the system will recognize the device as a standard Ethernet adapter once the SFP module and fiber link are active.
• Test and verify: Open your network settings and verify that a Gigabit link is established. Run a quick throughput test to confirm speeds align with your fiber transceiver’s capabilities, and ensure latency remains within acceptable bounds for your applications.

Frequently asked questions

• Q: What devices is this adapter compatible with?

  A: It connects USB-A devices to a fiber network through an open SFP port, enabling Ethernet over fiber for desktops, laptops, and tablets with USB-A ports. It is a versatile solution for office workstations, thin clients, and multi-user environments where fiber connectivity is desired without replacing entire workstations.

• Q: What speeds can I expect?

  A: The adapter supports 10/100/1000 Mbps Ethernet, delivering reliable Gigabit performance over fiber when paired with an appropriate SFP transceiver and fiber link. Actual speeds depend on the SFP module, fiber type, distance, and network conditions.

• Q: Do I need to buy a separate SFP module?

  A: Yes. The open SFP port requires a suitable SFP transceiver that matches your fiber type (singlemode or multimode) and distance. Pair with LC fiber cables and your existing fiber backbone to complete the installation.

• Q: Is this device power-hungry?

  A: It is designed to be powered via the USB connection, typically requiring no external power adapter for standard operation. If you operate under heavy network load or require additional cooling, monitor the device and ensure it remains within safe operating temperatures.

• Q: Can I use this adapter with any operating system?

  A: The adapter generally works with a broad range of operating systems that support USB-to-Ethernet devices and standard SFP-based Ethernet interfaces. In some cases, you may need to install or update drivers depending on the OS and the specific SFP module in use. Always verify compatibility with your OS and transceiver before purchase.
